Grotta che Parla (or better Rocca chi Parra Cave) is a cave opened in the NE sector of Montagna Grande. It is a small cavity 200 m long and 25 m deep, mainly oriented NW-SE. The cave develops on two levels, which mainly follow the bedding planes with a slope of 25°toward the SE. The passages show cupolas, pillars, pendants, likely related to the sulfuric acid processes. Its entrance opens in an artificial scarp of the still active Rocca chi Parra (Rocca che Parla) limestone quarry. The cave evolves in sequences of limestone and dolomitic limestones of Inici Formation (Upper Jurassic).
Interesting is the presence of greenalite, characterised by green to reddish colours, in association with gypsum, calcite, and dolomite. Greenalite could be linked to the presence of volcanic intrusive dikes in the Upper Jurassic Inici Formation and Fe-Mn encrustations (see Rocca chi Parra (Rocca che Parla) quarry). In addition, Montagna Grande represents part of a huge thrust-belt system overlapping terrigenous deposits containing pyrite.
